Austin's South by Southwest film festival has added two notable world premieres to its lineup. The fest (which begins March 11) will feature the first public screening of the much-discussed Mel Gibson film The Beaver, directed by Jodie Foster, and it will also debut Conan O'Brien Can't Stop, the long-rumored backstage documentary filmed during Conan O'Brien's Legally Prohibited From Being Funny on Television tour. "Did Conan O'Brien hit the road on a 32-city tour to connect with his fans or fill a void within himself?" ask the press materials. Existential!
